Lam-s Patent N 97,039, dated December 14,1so9

IMPROVED FERTILIZER OR GUAIN'Q.

I Hob-m A has Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

' -tr .oleum, and phenol, (carbolio acid,) or its equivalent,

each added successively, in the manner hereafter more fully specified.

Iniorder to enable those skilled in the science and art to apply my invention, I will proceed to describe The fish, or other animal matters, arefirst cut.1nto small pieces, then put on shelves in a vessel that can be made air-tight, except having an inlet and an out- I let.

. Connected with the inlet, at the top of the vessel,

is an air-pump or blower, by means of which hot air (I prefer that the temperature should be between 170 to 190 Ibahrcnheit) is introduced and forced to pass downward through the fish or animal matters, until about ninety per cent. of the water contained in said animal matter or fish is' extracted by the hot air.

This water that is carried off by the hot air is condensed in a condenser connected with the outlet of the vessel abovemeutioued;

When the operation has arrived at this point, the blast of hot air is cut oil from the vessel, and a current of hydrocarbon and phenol (carbolic acid) vapors is introduced into the vessel, and is forced to pass down through the animal matter or fish by means of a current of air.

The hydrocarbon and surplus phenol, having in solntion the oils and fatty matters, are condensed in a condenser attached to the outlet at the bottom of the vessel and collected.

The quantity of hydrocarbon and phenol to be added or used is regulated by the amount of animal matter or fislr being operated upon.

\Vheu the hydrocarbon and phenol-vapors pass through the vessel unafi'ccted, the supply is out off,

and the blast of hot air is again introduced into the vessel,'in order to'exp'el the remaining portion of water and hydrocarbon.

' The dry animal matter or fish is then taken out of the vessel, and ground, or otherwise pulverized, and the antiseptic fertilizer is ready for use.

The well-known antiseptic qualities of phenol (carbolic acid) remaining, in a degree, in the fertilizer, prevent-s furtherdecomposition, which can only take place at the expense of some of the valuable qualities of the fertilizer, if allowed to proceed.

The efiect of the carbolic acid is also of great benefit in destroying obnoxious insects and animalcule in the earth to which the fertilizer is applied.

Having thus described the process of preparing my fertilizer or guano,

What I claim as my invention, and desire tosccure by Letters Patent of the United States, is-- 1. The use of hot air, for the purpose and in the manner substantially as herein set forth.

2. The use of the hydrocarbons, or thcirequivalents, in the connection herein described, and for the purpose set forth.

3, The use of phenol,fli(carbolie acid,) or its cquiva-' lent, for thepurpose herein specified, and in the manner substantially as hereindescribcd.

4. As a new article ofjmanufiacturc, the antiseptic fertilizer, the process for the manufacture of which is herein set forth.

ORAZIO LUGO.
